My invention relates to corn-planters, and As they are well understood, it is believed it especially to that part of the seeding mechis not necessary to show and describe them anism which is known as the second drop here. The shank 11 of the runner 10 is hol 6'5 and which is adapted when used as a checklow and is provided at its top with a disrowing device to deposit in the Jfurrow the .E charge-tube 12, through which the seed is dehills oi corn which have beendelivered to it livered by means ot the seeding devices 1n ready for hilling by the seed-plates in the hopper the hopper 9. The shank 11 has a 'iront wall 13 and rear wall 14 and is open in the usual 7o The object ci? my invention is to provide a manner at the heel Jfor the discharge oi the new and improved system oi valves or second-drop mechanism which may be used corn.

in the runner from side to side and toward the In the drawings, Figure 1 is a side elevaopening in its heel. 8 5 19 indicates a rocking valve which is pivoted upon a pivot 2O near the top of the runner-shank. Referring to Figs. 6 and 7, where this valve is shown in detail, the rocking valve 19 is provided with a curved valve- 9o plate 21, the curve oi which is on the arc of a circle whose center is the pivot 20, and which is so journaled as to move back and forth across and close to the lower end of the dis charge-tube 12. The rearward end oi this 95 valve-plate is opened, as is best shown in Figs. 6 and 7, so as to provide a passage-way through which the seed may tall when the rocking valve is rocked forward. The closed portion oi the valve-plate 21 closes the openroe ing at the seed-tube 12 when the parts are in their normal position and receives upon it the grains oil seed deposited by the seeding devices in the hopper.

22 indicates a plate which is pivotally con- 105l nected at its upper end with the rearward arm oi the rocking valve 19 and is provided near its center with a cam portion 23, which row-opener an conducting-tube or shank with one oi its sides removed ior the purpose oi showing the operating mechanism. Fig. 2 is a view oi a part of the runner or furrowo ener and conducting-tube or shank with t e side removed, showing the dropping devices in their last position when the corn is being dropped. Fig. 3 is a view ol a portion of the runner or iurrow-opener and conducting-tube or shank, showing the mechanism arranged tor drilling. Fig. f1 is a section on line 4. f1 of Fig. 3. Fig. 5 is an enlarged detail, being a view oi a portion oi the rocking seed-valve in the tube. Fig. 6 is an enlarged detail, being an isometric view oi the rocking seed-valve with a portion of the plungerearm; and Fig. 7 is a detail, being a view of the rocking seed-valve in section an showing portions oi the arms connected there to Referring to the drawings, S indicates poris adapted to bear against an inward-projecttween the lower end of the plate 35 and the ing cam portion 24 on the inside surface of upper surface of the plate 18, thus forming a the rear wall of the runner-shank 11. closure when the plunger is pushed vdown- 25 indicates a rigid plate which extends ward and backward along the plate 18 to dis- 5 across the upper portion of the runner-shank charge the accumulated seed. 7.o

inside from side to side a short distance to 36 indicates a plate which is pivoted at its the rear of the seed-tube 12 and between the lower end immediately above the plate 35 lower end of which and the cam portion 24 and which extends across the runner-shank the plate 22 moves. inside from side to side. The plate 36 is of 1o he cam portions 23 and 24 are so shaped such length that its upper end when secured 75 in the position shown in Fig. 1 contacts the lower end of the plate 25 and when moved forward into the position shown in Fig. 3 its upper end contacts the plate 33. A pin 37 upon the plate 36 projects through a slot 38 8o in the side of the runner, where it is engaged by a suitable latch 39 (shown in dotted lines in Figs. 1 and 2) to lock it in either position.

It will be seen from the above description that the plates 25, 36, and form the rear 85 wall of the discharge-tube in the runnershank when the devices are used for checkrowing`that is to say, when they are in the position shown in Figs. 1 and 2-and that the when the check-row forks are in their normal position before being acted upon by the knots 1 5 on the tappet-wire`the. lower end of the zo check-rowing devices into the position shown 25 the rear wall of the runner-shank, as shown the discharge-tube when the mechanism is used for drilling`that is to say, when the devices are in the position shown in Fig. 3.

he operation of the device is as follows: When the mechanism is used for check-rowing, the plate 36 is locked back in the position shown in Figs. 1 and 2. The normal position of the parts is that shown in Fig. 1. The machine being in operation, a suitable e rocking valve 19 is provided with a forward-projecting arm 26, which is forked into two portions, each one of which is slotted 3o as at 27. v

28 indicates an arm on the rock-shaft 15, through which passes a pin 29, which engages thevslots in' the forked arm 26. When the check-row fork is thrown backward by the 3 5 operation of the knots on the tappet-wire, the

' seeding devices in the hopper in any welland the valve-plate 21 of the rocking valve 19 is rocked forward, so as to bring its open portion underneath the discharge-spout 12, al-

4o lowing any grains of corn that may have been 'delivered to it by the action of the seeding devices to fall down the interior of the runnerl.shank toward the sloping shelf 18.

30 indicates a plate which moves between 4 5 'the side walls of the runner-shank 11 and is provided at its upper end with a fork 31, i which is adapted to lie between the two -arms 26 of the rocking valve 19 with the fork engaging the pin 29 on the rock-arm 28.

5o short distance below its top the plate 30 is provided with `a cam portion 32, which is` adapted to bear against the lower end 'of a plate 33, located in the upper portion of the runner-shank below the pivotal point of the 55 rocking valve 19. The lower end of the plate 30 is curved downward and backward in a shape substantially parallel with the surface of the sloping platef18 and is provided at its lower end with a plunger 34.

co 35 indicates a plate which is secured beforms the top closure of the devices. When the tappet on the tappet-wire 17 contacts the fork-lever 16 and drives it backward, the rocking valve 19 is thrown forward, its open portion coming below the discharge-spout, and the seed falls into the interior of the dis- 1 1o charge-tube. As the rocking valve 19 or upper closure is rocked forward the plate 30 is moved downward, and the cam portion 32 bearing against the lower end of the arm 33 the plunger-head 34 is moved downward on 115 the sloping plate 18 and kept in contact therewith by the cam action above described. As it passes downward under the lower end of the plate 35 it closes that opening, forming a second or middle closure and preventing any 12o grains of corn from being dribbled outy through the heel of the-runner. At the eX- treme of the movement the plunger-head 34 is in the position shown in Fig. 2, nearly at the rear of the shelf 18. At the same time the 12 5 plate 22 is drawn upward and moved backward away from the lower end of the shelf 18, opening the third or lowest closure. At the sizethat when slid along the sloping plate 18, end of this operation the parts are in the po- K 6 5 as hereinafter described, it fills the space besition shown in Fig. 2. As soon as the tappet .15o

plates 33, 36, and 35 form the front wall of 90 number of grains of corn delivered by the rooon the tappet-wire slips from the fork-lever the fork-lever is instantly returned to its first position by the usual springs and the parts resume the position shown in Fig. 1. Usually this will be done so quickly that the corn dropped through the tube 12 by the opening will hardly have had time to fall against the upper surface of the plunger` before it is again withdrawn by this instantaneous returning of the fork mechanism and the lower end. of the shelf 1.8 closed by the plate 22 being returned into the position shown in Fig. 1.. Whether any corn has been caught in the second closure or not, however, this movement drops the accumulated corn upon the shelf ready to be deposited in the ground by the next operation of the plunger. Upon the contact of the next tappet upon the fork-le ver the movements above described are repeated. The hill of corn laid upon the shelf 18 as above described is pushed or kicked out backward through the heel of the runner ofi the shelf 18 at a speed which will compen sate for the forward motion of the machine and prevent the straggling of the corn as it drops, the charge accumulated by the seeding mechanism in the hopper being dropped to take the place of the charge `iust pushed out, as above described. When it is desired to use the planter as a drill, the swinging plate 36 is moved forward into the position shown in Fig. 3 and the fork of the checkrower moved back and tied or otherwise secured in the position shown in Fig. 3. This will bring all the parts into the position shown in said Fig. 3, the open portion of the rocking valve 19 being below the dischargetube 12, and the seed will be dropped as the seeding devices in the hopper operate down through the channel formed between the plates 35, 36, and 25, which then form the Y front wall of the seed-channel, and the plate 22 which thus forms the rearwall of the seedchannel.

l. have shown only one runner furrow-opener of the corn-planter. .lt will of course be understood. that in ordinary practice there are two of thesev runners and seedboxes, one upon each side of the planter; but as they are duplicates of each other the description of one serves for a description of both. have not shown the cornplanter itself, as my invention is confined to the parts shown, and the corn-planter being of any well-known and approved form and description will be readily understood in its structure and operation.

That which I claim as my invention, and desire to secure by Letters Patent, is

1.. in a corn-planter, the combination with check-rower mechanism, a seedboX and a hollow runner-shank, of an opening between said seedboX and the top of said runner'- shank, an upper valve controlling said opening and forming an upper closure, a shelf opening to theheel of said runner-shank, a l

plunger adapted to move along said shelf and discharge seed therefrom to the ground, an opening above said shelf adapted to be closed by said plunger to form an intermediate closure, a valve-plate adapted to close against said shelf to form a bottom closure, and connections between said check-rower devices and said upper valve and. said valve-plate and said. plunger whereby when said upper and lower closures are opened by the action of the eheck-rower mechanism the plunger will close said intermediate closure and force the seed from the shelf and when said upper and lower closures are closed said intermediate closure will be open.

2. In a corn-planter, the combination. with a hollow runner-shank, a sloping shelf at the heel of the runner, and an opening for the passage of seed at the top of the shank, of a valve adapted when operated to alternately open and close said opening, clieclcrower mechanism connected with said valve, a plate pivotally connected at its upper end with said valve and having a plunger-head at its lower end adapted to move back and forth on said shelf when said check-rower mechanism is operated, an intermediate closure above said plate adapted to be closed by said plunger when moved to discharge the seed, and a valve-plate pivotally connected at its upper end with said valve and adapted to close against said shelf when said plunger is moved and to be lifted therefrom when said plunger moves along said shelf to disn charge the seed, substantially as described.

3. In a corn-planter, the combination with a hollow runner-shank, a sloping shelf at the heel of the runner, and an opening for the passage of seed at the top of the shank, of a rocking valve adapted to swing past said opening and to alternately open and close the same when operated, check-rower mechanism connected with said rocking valve, a cam plate pivotally connected at its upper end with said rocking valve and having a plungerhead at its lower end, a bearing in said shank adapted to bear upon said cam-plate andv cause said plunger-head to slide back and forth along said shelf when the check-rower mechanism is operated, a series of plates eX- tending across the opening in said runner from side to side to form a rear wall for the tance above said shelf adapted to be closed by said plunger, when moved to discharge the seed., to form an intermediate closure, a cam-plate pivotally connected at its Lipper end with said rocking valve, and a bearing on said runner-shank adapted to bear against said cam-plate and close the lowei end of the same against said shelf to form a lower clof sure when said check-rowing devices are in their normal position, substantially scribed.
